使用Jquery从字符串下载pdf文件

Question

All,

I have a PHP5 application written with Zend Framework and MVC. On my home page, I want to incorporate the functionality to download a dynamically generated pdf file. The way this is done is:

1. User clicks "download file" link.
2. On Click, an AJAX call occurs to a PHP controller, which takes the form data, generates the pdf and returns it as a string.
3. My javascript function now has the pdf string.
4. How can I display the user an "Open/Save" dialog to download the pdf file from javascript?

I have the following code:

<script type="text/Javascript">
   $('#dlcontent').click(function(e) {
      $.ajax({
                type: 'POST',
                url: "/downloads/dlpolicies",
                data:  $("#frmMyContent").serialize(),
                cache: false,
                dataType: "html",
                success: function(html_input){
                    alert(html_input);  // This has the pdf file in a string.
                    //ToDo: Open/Save pdf file dialog using this string..
                }
            });
});
</script>

Thanks

The simplest way of doing it is open a new window with URL to pdf string.
